We run a 30+ item construction-specific checklist that most accountants don't have. You get a professional handoff pack with every deduction, relief, and allowance documented and ready to file. Your accountant just submits it.
High-street accountants are trained to process returns — not optimise them for CIS subcontractors. They handle hairdressers, landlords, Deliveroo riders, and you. All with the same generic checklist.
They don't ask about your mileage log. They don't know that parking and tolls are claimable on top of the 45p rate. They've never heard of the flat-rate laundry allowance. They don't check whether your contractor deducted CIS on materials when they shouldn't have. They file what you give them — and you don't know what you're missing.
This isn't a list of suggestions. It's a professional, ready-to-file handoff pack with every number calculated, every document attached, and every claim referenced against HMRC guidance.
Prepared for [Client Name] | Tax Year 2025/26
All PDS slips reconciled. Gross income, CIS deducted, materials breakdowns. Cross-referenced against HMRC CIS records. Discrepancies flagged.
Every allowable expense identified, categorised by HMRC heading, with supporting evidence attached. Travel, tools, PPE, phone, insurance, training, home use — the lot.
Mileage log reconstructed from site records, bank transactions, and client info. Total business miles calculated. Mileage vs actual cost comparison — whichever saves more.
Flat rate claim calculated, PLUS separate fixed-cost claims (council tax, insurance, mortgage interest) most accountants don't know you can stack on top.
Any vans, plant, or major equipment identified with purchase dates, prices, and AIA calculations. Ready to enter on the return.
Marriage allowance eligibility + backdate calculation. Pension relief. HICBC mitigation. Student loan thresholds. Every personal angle checked.
Plain-English summary of everything found, with HMRC manual references for anything non-standard. Your accountant can verify every claim in minutes.
We're not replacing you. We're making your job easier and your client happier. The handoff pack is designed to slot straight into your workflow — categorised by SA100 headings, with HMRC references on every non-obvious claim. Your client gets a bigger refund. You spend less time on prep. Everyone wins.
Photo them on your phone. WhatsApp them over. We accept photos, PDFs, screenshots — whatever's easiest. No printing, no posting.
We send you a short questionnaire built for subbies — not generic accountant questions. Mileage, tools, training, working away, home use, spouse, van. Takes about 15 minutes. We chase the gaps so your accountant doesn't have to.
Our team cross-references everything, runs the 30+ item checklist, calculates every claim, and assembles the professional pack. Every number backed by evidence. Every non-obvious claim referenced against HMRC manuals.
You get the pack as a PDF. Forward it to your accountant or give us their email and we'll send it with a cover note. They file it. You get more back. Done.
Not because they're bad. Because they've got 400 clients across 50 different industries and a generic checklist that doesn't ask a groundworker about his CPCS tickets.
No mileage log means no claim. We reconstruct it from site records and bank data.
Accountant put it on "motor expenses." No AIA claimed. That's a one-year write-off they missed entirely.
Most don't know the flat rate and fixed costs can be claimed together. We calculate both.
Partner earns under £12,570? Free money. Accountant never asked.
CIS should only apply to labour. We cross-reference every PDS breakdown.
The long tail of small claims that add up to thousands. We catch every one.
The pack typically uncovers £3,000–£12,000 in extra deductions. Your accountant's fee stays the same. The only difference is the size of your refund.
Both packs are a deductible business expense on next year's return.
If our pack doesn't identify at least £500 in extra deductions your accountant wasn't already claiming — you pay nothing. We refund you in full, no questions. We're that confident in the checklist.
Pick your pack, complete the checklist, upload your docs. We run 30+ construction-specific checks and have your handoff pack ready within 48 hours. You give it to your accountant. Everyone's happy — especially your bank account.
15 minutes of your time. A construction-specific checklist your accountant doesn't have. Thousands more back in your pocket. From £97.
